This already saves a lot of disk space, because the class issues less whitespace than our own code. Plus, switching to binary data will be very easy now. [[Imported from SVN: r9976]]

Previously, the number of multigrid transfer operators was always equal to the number of grid levels minus one. That worked out correctly when doing first-order FE spaces. However, for higher-order spaces, the up-most transfer operator transfers from the higher-order space to a first-order space _on the same grid level_. But since the total number of transfer operators was grid levels minus one, this implied that the coarsest grid leve was never used, and the coarse grid solver would operate on the second-coarsest grid. This patch adds the extra transfer operator in this case. That means we now call the coarse grid solver on smaller problems, which makes a noticeable run-time difference. [[Imported from SVN: r9964]]

Normally, the two different level grid views. Previously we used the same one to compute the localToGlobal renumbering for boths rows and columns. Of course that screws up the numbering. I am not quite sure when that got introduced. I may have gotten in fairly recently, after the upstreaming of the GlobalIndexSet classs. [[Imported from SVN: r9962]]

May happen when the matrix is singular. UMFPack doesn't like that. [[Imported from SVN: r9958]]

It tentatively uses the UMFPack direct solver, disregarding the obstacle. If that leads to an energy-decreasing, admissible new iterate, then good. Otherwise, it falls back to IPOpt. [[Imported from SVN: r9957]]

This is a first step towards having trust-regions with different scaling in the different components. Kinda paradox to introduce an explicit radius in order to move away from a single radius. But I want to pretend to the outside (for the time being) that there is a single radius... [[Imported from SVN: r9950]]

To really make sure I am doing the infamous L-shape example like the people before me did I need point loads. Being a mathematician I am no particular fan of point loads, so they may go out again eventually. [[Imported from SVN: r9942]]

This is the interpolation method used by Ingo Münch and Wolfgang Müller for Cosserat materials. My implementation is only able to do all that I needed for the illustrations in the GAMM Rundbrief article. I'm sure there'll be more fixes needed if you actually want to do finite elements with this. [[Imported from SVN: r9940]]

For example, I'll use this for finite-strain elasticity problems. Some of this should be in dune-fufem and/or dune-pdelab, but for the time being it's easier to have it here. [[Imported from SVN: r9939]]

This form allows to set the shear correction factor kappa. It is still not ruled out that we need to twiddle with this factor in order to weaken the material a little bit. [[Imported from SVN: r9937]]
